i haven't opened this particular package yet, but Energizer batteries have always worked for me in the past, so i see no reason to assume otherwise. for whatever it's worth, i use either Energizer or Duracell batteries for everything, and stay away from mongrel brands.

They are working well but only time will tell how long they work for.

Exactly what I needed. Thank you!

Working great, just wish they were not so expensive

I would of rather purchased member mark batteries, they weren't available

Much better then those "Leaky" Duracells!!!

Great Batteries work as they should Last a long time.

The date is only 3 years away but price is right. These batteries are a great value for the money for smoke detector.

I bought these for our fire detectors, you know the ones that seem to always die in the middle of the night (beep, beep, beep, beep). I replaced the batteries in 2 of the detectors two weeks ago and they are already dead (insert annoying beep, beep, beep, beep . . . ). Not sure what happened to these batteries before I got them but they are not good!

They are selling batteries that are 2-3 years old so the shelf life is NOT 5 but 2 years (??). And only time will tell if they last that long.
